QUADRA-TRAC I® FOUR-WHEEL DRIVE
Quadra-Trac I® Operating Instructions/Precautions - 3.6L Only
• The Quadra-Trac I® is a single-speed (HI range only) transfer case, which
provides convenient full-time four-wheel drive. No driver interaction is
required. The Brake Traction Control (BTC) System, which combines
standard ABS and Traction Control, provides resistance to any wheel that
is slipping to allow additional torque transfer to wheels with traction.

FOUR-WHEEL DRIVE
Quadra-Trac II®/Quadra-Drive II® Operating Instructions/
Precautions
• The Quadra-Trac II®/Quadra-Drive
II® transfer case is fully automatic
in the normal driving 4WD HI
mode. The Quadra-Trac
II®/Quadra-Drive II® transfer case
provides three mode positions:
• 4WD HI
• NEUTRAL
• 4WD LOW
• This transfer case is fully
automatic in the 4WD HI mode.
• When additional traction is required, the 4WD LOW position can be used
to lock the front and rear driveshafts together and force the front and
rear wheels to rotate at the same speed. The 4WD LOW position is
intended for loose, slippery surfaces only. Driving in the 4WD LOW
position on dry, hard-surfaced roads may cause increased tire wear and
damage to driveline components.
• When operating your vehicle in 4WD LOW, the engine speed is
approximately three times that of the 4WD HI position at a given road
speed. Take care not to overspeed the engine and do not exceed 25 mph
(40 km/h).
NOTE:
• If shift conditions/interlocks are not met, or a transfer case motor
temperature protection condition exists, a “For 4x4 Low Slow Below
5 MPH or 8 KPH Put Trans in N Press 4 Low” message will flash from the
Electronic Vehicle Information Center (EVIC).
